FOUNDER · LICENSED ELECTRICIAN · NABCEP CERTIFIED
A Trusted team of professionals
Joe Lopez founded Sunny Solar Power after more than 15 years handling residential and commercial solar systems throughout San Diego County. He holds California contractor license #1042628 (classifications B, C-10, and C-46) — which means when he cleans your panels, he's also the person qualified to flag anything electrical that needs attention.
Most cleaning companies send a crew with a hose. Joe's team arrives with a licensed electrician who actually reads your monitoring data, checks your connection points, and tells you what he finds — not just what you want to hear.
We service systems we didn't install. If your original installer is gone, that's exactly the kind of job we take.
More Than a Rinse — A Full Service Visit
WHAT WE DO
Every cleaning appointment includes a visual inspection of your panels, mounting hardware, and wiring connections. You get a report, not just clean glass.
Panel Surface Cleaning
Deionized or purified water wash removes dust, bird droppings, pollen, and residue that block light from reaching your cells. No soaps or chemicals that leave film.
Visual Panel Inspection
We check for micro-cracks, delamination, discoloration, and soiling patterns that indicate a panel is underperforming — things cleaning alone won't fix.
Connection & Mounting Check
Loose conduit, corroded wire connections, and compromised racking are safety and performance issues. A licensed electrician checks them on every visit.
Monitoring & Output Review
We pull your system's production data before and after cleaning so you can see the actual output difference — not a guess.
Inverter & System Diagnostics
If your monitoring shows a panel or string producing below expected levels, we diagnose before we leave. No scheduling a second visit to get the answer.
Post-Service Report
You receive a written summary of what we found, what we cleaned, and any recommended follow-up. Useful for warranty documentation and home sale records.
WHY IT MATTERS
Dirty Panels Are a Silent Performance Problem
In San Diego County, dust, marine layer residue, and bird activity accumulate fast. Your inverter keeps working — but your output doesn't.

Additional equipment cost — cleaning recovers output you already paid for
Every kWh your dirty panels fail to produce is a kWh you buy from SDG&E at peak rates. Cleaning pays for itself faster than most people think.
WHO WE HELP
We Service Any System — Including Ones We Didn't Install
✓ Homeowners with existing solar (any installer)
✓ Buyers who inherited a system with a home purchase
✓ Customers whose original installer is no longer in business
✓ Property managers with multiple rooftop systems
✓ Anyone who hasn't had their system serviced in 2+ years
Most solar companies will only clean systems they installed. Sunny Solar Power takes the calls others pass on.

"Joe showed up personally and diagnosed a problem three other companies said they couldn't figure out. Turned out the issue was with SDG&E's transformer, not our system. He documented everything and forced them to fix it."

"We were desperate to re-connect our older solar panels after a remodel and no one wanted to bother with us. Joe and Ramon at Sunny took such good care of us and their office manager Erica is AWESOME as well. We are up and generating!! THANK YOU!"

"Great work. Joe is awesome. They were able to fit my smaller job in during the crunch for the NEM2 deadline. I recently had an issue with communication from my inverter to app. I notified sunny solar and Joe came out the Tuesday before Christmas eve and fixed the issue."
